Questions about this article

Can I charge the battery by inserting the device's plug in the bike's plug on the left side of the console?
Yes, you can charge your battery directly with the bike outlet on the left side (for this you have to order article number 90013).
Or you can also connect it directly to the battery, using article number 208-037-1.
You can also order the eye cable for the connection directly to the battery separately with article number 208-03-71.

Does the plug fit into all sockets? Also USA, UK, Australia, Asia?
No, there is no plug which fits all sockets. We are a German company and our plugs fit our sockets. But this is no problem. Just get a travel adapter and it should work fine.
